Got an old SxS I'm working on and want to go the cold blue route with it. I'm spending a lot of time in finishing the metal and trying to get the prep work right. I've heard different thing's on different cold blue's so want some option's...I'm leaning towards Brownells Oxpho Blue. Anybody use this stuff and how were the results...

All I have ever used is Brownells Oxpho-Blue. I remove the old coating with a buffing wheel and a buffer bought at Sears. After buffing I scour the polished barrell with a non chlorinated scouring powder. I raise the temperature of the hot water to rinse the scouring powder off and to raise the temperature of the barrel between coats. I apply 7 coats of Oxpho Blue wiping it off with 0000 steel wool between coats. After the final coat I apply unboiled linseed oil and let it stand for two days then apply Hoppes Gun oil. I have done seven 870 Expresses this way as well as some of my own guns. The Ospho-Blue holds up very well with seven coats. Ned S

Thanks for the replies. I'm finding the metal prep work a challenge enough, having to deal with some very minor pitting on the barrel surfaces. The gun is over 80 years old so it's to be expected, but I want to make it look right.
